Abstract

The invention relates to the technical field of laser processing, and discloses an imaging system and method of a square scanning head of a dual-light-path dual-imaging visual galvanometer. The imaging method comprises the steps that external laser beams reach the galvanometer through a second lens, and act on a to-be-marked object through a first lens after being reflected by the galvanometer, and then the to-be-marked object is marked; a white light source emits an illuminating light path to brighten the to-be-marked object, the illuminating light path is reflected to the first lens, then partially reflected to a large-visual-field image acquisition module through the first lens, and used for acquiring the overall image of the to-be-marked object, coordinates of an image in a pre-marking position are obtained accordingly, the swinging angle of the galvanometer is further obtained, and the galvanometer is driven to rotate by the swinging angle; and part of the illuminating light path reaches the galvanometer through the first lens, enters a small-visual-field image acquisition module after being reflected to the second lens, and is used for acquiring detailed images of the to-be-marked object, and the accurate coordinates of the pre-marking position are obtained according to the detailed images. By adoption of the imaging system and method of the square scanning head of the dual-light-path dual-imaging visual galvanometer, the marking precision of the square marking head can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of laser processing, and more specifically relates to an imaging system and an imaging method for scanning a square head with dual optical paths and dual imaging visual galvanometers. Background technique [0002] The traditional marking square head has no visual aid, and it is in the state of blind typing. It is usually marked by a fixture or a fixed coordinate position. For high-precision marking requirements, the traditional marking square head has many factors. , which is difficult and complex. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems existing in the prior art, and provide an imaging system and imaging method for scanning square heads with dual optical paths and dual imaging visual galvanometers, which can greatly improve the marking accuracy of marking square heads. [0004] In order to solve the problems raised above, the tech...
